Methods: Eighty BPH patients were divided into two groups randomly by double blind, double simulated and active control parallel study trials. 方法:80例诊断为BPH的病人,随机分为试验组40例和对照组40例。
A method that actual system was simulated with experimental data of orthogonal test as learning samples was adapted and the object that complete trials were simulated was achieved. 采用以正交设计试验作为学习样本模拟真实系统的方法,来模拟完全试验;
